Quite a few of us are running jailbroken devices, and can run just about anything we please.
Additionally, it costs a one time $100 charge to become an Apple developer (assuming you already have a mac), and then you can deploy everything even without a jailbreak. Given that a new device costs upward of $650 (let's ignore "subsidies" here), another $100 to get locally "open" the device is, for some of us, a reasonable expense.
